Reaction Steps

To a solution of 7-(2-hydroxyethyl)-2,3-dimethoxy-4,5,6,7,8,9-hexahydro-1H-benzo[a]cycloheptene-1,4-dione (103 mg), p-cyanophenol (127 mg), triphenylphosphine (126 mg) in THF (2 ml) was added a solution of diethyl azodicarboxylate (90 mg) in THF (1 ml) at room temperature. The reaction mixture was stirred at room temperature for 2 hr and then concentrated in vacuo. The residue was purified by alumina column chromatography (ethyl acetate:hexane=1:4) and then with recrystallization from ethyl acetate-hexane to obtain the entitled compound (118 mg).
